Freiburg

The County of Freiburg lay in the Breisgau and grew from the Zähringen inheritance. In 1337 Count Conrad II ruled Freiburg, whose citizens had long disputed the counts' authority.

In 1368 Freiburg bought its freedom and placed itself under Habsburg protection. The counts retained their Badenweiler estates, but the last count, Johann, bequeathed them to the margraves of Hachberg-Sausenberg in 1444.
